Quincy Transmission Expansion Plan (QTEP) Grant Public Utility District

Power.
Growth.
Opportunity.

The Quincy Transmission Expansion Plan (QTEP) is a proactive approach to managing the county's power system.

Implementing the Quincy Transmission Expansion Plan will increase capacity, create redundancy, reduce outages and help keep rates low.

A power grid for your future.

The demand for electricity in Grant County is rapidly growing beyond the capacity of Grant PUD's energy resources.

We have a plan.

The QTEP Project will include six transmission line segments one mile to 32 miles in length, one new switchyard, expansion of the existing Mountain View substation, and expansion of existing Wanapum switchyard.

  • Increase Capacity

    Our projections show the next decade will bring even faster growth, as more families arrive, business and industry expands, and emerging new sectors (like EVs). This will require more electricity than we can currently supply. The QTEP projects will increase the load limit from approximately 300MW to 650MW to serve this need.

  • Create Redundancy (a good thing!)

    Additional transmission lines increase the pathways that power can flow into the communities of Grant County. Redundant connections provide additional reliability in the Quincy area.

  • Reduce Outages

    A more robust transmission system with multiple pathways for electricity to travel throughout the county allows us to perform maintenance and make repairs without lengthy customer outages.

  • Keep Rates Low

    Industries purchasing power above Grant PUD's cost with expanded transmission services will provide revenue to keep rates at or below cost for core customers (Residential, Ag, Small Business).

QTEP Projects

Grant PUD identified potential projects that would increase electrical capacity and reliability in the Quincy area to meet future energy needs.

This new line would connect the existing Columbia to Rocky Ford 230kV transmission line to the existing Mountain View substation located on the west side of Quincy and just north of SR 28.

Wanapum to Mountain View is a 32-mile, 230kV transmission line from the Wanapum switchyard to the Mountain View substation in Quincy.

This new line would connect the existing Columbia to Rocky Ford 230kV transmission line to a proposed Monument Hill switchyard northeast of the intersection of Road 11 NW and Road O NW.

This new line would complete a 230kV transmission loop that would provide a second transmission source to existing and future substations in the east Quincy area. The line would begin and end at the Monument Hill switchyard.

The Mountain View to Monument Hill 230kV transmission line is separated into four line segments. The western portion will connect Mountain View Substation to the Mountain View Tap 230kV line. The eastern portion will extend from the future Quincy Foothills Provisional 230kV Tap to the future Monument Hill Switchyard.

The Mountain View Loop #1 230kV transmission line will extend the existing transmission line approximately 1.3 miles into the existing Mountain View Substation.
